The first-ever Firefly Festival promises to be a less overwhelming alternative to heavyweights like Bonnaroo and Lollapalooza, which usually have between 100 and 200 bands on their rosters. But don’t go thinking that this will be a small event. There will be lots of food and attractions on the 87-acre Woodlands grounds, including hot air balloon rides, a vintage-themed arcade, and an interactive art gallery.

Thousands of “Early Bird” passes went on sale April 5 and sold out in minutes.

Regular three-day passes are still available for $218, and include access to all shows at the festival.

Attendees will be able to camp on site, park recreational vehicles, and even purchase a “glamorous camping” package, which includes real beds, furniture, private showers, and an air- conditioned lounge.

For those who don’t feel like driving to the event, the Rock & Bus shuttle will offer round-trip service to Firefly from the District, Alexandria, Annandale, Springfield, Annapolis and Baltimore.

Another way to experience the festival is through volunteer work. Firefly is still looking for volunteers to help with everything from food service to parking patrol.

Music festivals have come a long way since Woodstock — they are safer, cleaner, and more complex — but the experience of hearing dozens of favorite bands in one place continues to be a simple formula for success.

Firefly brings that formula much closer to home for East Coast musicphiles.
